Is Slowbro Good in Let's Go Pikachu & Eevee Playthrough?

Slowbro tanks physical hits and fires back with Psychic and Water coverage that handles Giovanni, Bruno, and Blaine. The raw bulk makes it a mainstay from evolution through the Champion fight. Mega Slowbro in postgame turns it into a physical fortress that almost nothing breaks through.

Fastest Path

The best route is Catch Combo at full boosts, about 1 in 274 on each try. Tune it below.

Step 1 · Encounter Method2 in Let's Go Pikachu & Eevee

Catch Combo: Catch one species back-to-back. A Lure stacks on top of a 31-plus combo.

Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.

How is this calculated?

Every encounter has the same shiny chance, the Shiny Odds Per Try shown above. Each one is a separate roll that does not care how many you have already done, so the more you hunt, the higher your overall chance of at least one shiny. The formula below turns your odds and your number of tries into that combined chance.

chance after N tries = 1 − (1 − p)^N,  where  p = 1 / odds per try

Example at 1 in 8,192 (classic full odds): about 864 encounters for a 10 percent chance, 5,678 for 50 percent, and 18,862 for 90 percent.

The table above flips that around: it shows how many encounters it takes to reach a 10, 25, 50, and 90 percent chance at your current odds. Turning on boosts like the Shiny Charm, sandwiches, or chains improves your odds, so the encounter numbers drop.

These are estimates, not promises. Most games have no pity counter, meaning no guaranteed shiny no matter how many you hunt, so even Very Likely is not guaranteed: some hunters find one early, others go well past that point.

Slowbro Weakness

Let's Go Slowbro Best Moveset

Mega Slowbro locks in 180 Defense, creating something nearly indestructible on the physical side even without the Shell Armor crit protection it has in other games. Without the Mega, 100 Sp. Atk at 30 Speed means the moveset trades last but hits respectably through Water/Psychic TermStab. The Mega is where the defensive identity becomes real.

Relaxed raises Defense and lowers Speed. Madam Celadon sets this nature when you pick Yellow, then Pink. It costs 10,000 Pokedollars and lasts for the rest of the day.

Candy for Slowbro

Slowpoke Candy raises every stat, but only Slowpoke and Slowbro can eat it. The stat candy that goes with Slowbro is Tough Candy (Defense), and any Pokemon can eat it; Tough Candy L needs level 30 and Tough Candy XL needs level 60 or higher.

Master Trainer

Haruka battles with one level 75 Slowbro that knows Disable, Calm Mind, Yawn and Shadow Ball. It takes extra damage from Electric, Grass, Bug, Ghost and Dark moves. Win to earn the Slowbro Master title. Find Haruka on Route 21.

Moves List

Most of Slowbro's flexibility comes from TMs. Same-type output runs through Dream Eater and Surf, but Normal and Ice and the rest of the TM pool push it from predictable to genuinely threatening.
